Title:
APPARATUS AND CASSETTE FOR LIQUID VENT-TYPE SURGICAL OPERATION
Document Type and Number:
Japanese Patent JP3803535
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an apparatus for a surgical operation in which the excess of a suction vacuum can be vented quickly without causing a pressure change.
SOLUTION: A pressure inside a collecting chamber 29 is maintained nearly to be atmospheric pressure. When a suction vent line 24 is opened, a liquid flows to a suction line 20 from the collection chamber 29. In a suction apparatus 10, a second cleaning fluid device is not required, and a pressure surging operation to a cleaning fluid line is reduced as far as possible. A bad influence is not given to the fluid characteristic of the suction apparatus 10. In addition, different vent pressures can be realized when the vertical position of the reservoir 29 with reference to the suction line 20 is changed.
